The impish kernel returns "not supported" when fallocate is used in the way mysql does it. That makes mysql aware of the problem, and switch strategies, and it works.
The jammy kernel is saying all is fine with the call and its results, but it isn't. Mysql, or any userspace, shouldn't be second guessing the kernel. > Please let me know if setting zfs_fallocate_reserve_percent=0 is a workaround for now. We will test it and put in the release notes as a workaround if it works. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1969247 Title: fallocate with FALLOC_FL_ZERO_RANGE produces zero-size files on zfs in Jammy To manage notifications about this bug go to: https://bugs.launchpad.net/zfs/+bug/1969247/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
